APPARATUS FOR ELEVATING WATER.

Specification of Letters Patent.

Application filed October 24, 1911. Serial No. 656,521.

To all whom'z't may concern:

Be it known that I, NAT H. FREWN, a citizen of the United States, residing int-he city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Apparatus for Elevating Water; and I do declare the following to be a full, clear, and exact description of'the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters ofreference marked thereon, which form a part of this specification.

My invent-ion relates to improvements in apparatus for elevating water, in which is involved the principle of introducing air into a series of compartments of relatively small cross sectional volume, whereby the water forced upwardly through said compartments has its specific gravity reduced by the formation of air bubbles, resulting from the introduction of the air thereto. The various compartments, through which. the water is raised, are formed within a standpipe in communication with a source of water supply, the outermost water-elevating compartment-forming member being suitably spaced from theinner surface of the standpipe, provision being made for introducing air into the standpipe around the outermost compartment-forming member, the upper extremity of 'the standpipe, through which the compartment-forming members'protrude, being provided with a stuffing box forming a fluid-tight joint.

Space within the standpipe is in communication with the several compartments, through which the water is elevated, in such a manner as to supply the said compartments with relatively small jets of air, which mingle with the water the latter passes upwardly through the various compartments, reducing specific gravity of the water, as aforesaid.

Having briefly outlined my improved construction, Iwill proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof.

In this drawing: Figure-1 isa vertical section, taken through my improved apparatus. Fig. 2 is a similar view of one section or member'constituting the series of compart-ments within the standpipe. In this view, the constru'ctionjs shown on a larger scale, and is a section taken on the line 2'-2 of Fig. Fig. 3 is a cross sect-ion, taken on the line 33, Fig. 2.

The same reference characters indicate the same parts in all the views.

V Let the numeral 5 designate a standpipe, whose lower extremity 1s in communication with a source of water supply. Arranged within this standpipe. is located a number of tubes of varying diameters, concentrically arranged one within the other, the outermost tube 6 being suitably spaced from this standpipe to form 'a compartment 7 A tube Sis arranged within the tube 6, forming a compartment 9 between the tubes 7 and 8 while, within the'tube 8is located a comparatively small tube 10, forming a compartment 11 between the tubes 8 and 10, the tube 10 forming a central compartment 103;. The portion of these tubes within the standpipe may be composed of castsections 12 connected by radially-arranged webs 13, the outerf I most part 14: of eacn section having flanges 1:) at the top and bottom having perforations 16 to receive bolts 18, which connect the meeting flanges of the various members.

standpipe is provided to form a fluid-tight joint. The various tubes constituting The aforesaid compartments are equipped with air jetnozzles 20, 9.1 and 22,. which, at their outer extremities, are in communication Patented Aug. 20, 1912.

with the air space 7 within the standpipe, whereby jets of air are. introduced to the various compartments to which the water is raised for the purpose of forming air bubbles in the water and diminishing its specific gravity. The different pipe sections, except where the members 12 are employed, are

- structure may be of any suitable formation.

compartment-forming pipe structure The upper extremity of the compartmentformin pipe structure protrudes into a reservoir "24', the tops of the pipe members 8' and 10 being equipped with outwardlyprojecting flanges or hoods 25 and 26, whereby the water, escapingfrom the compartments 9 and. 11, is deflected downwardly within the reservoir. The bottom of the reservoir is provided with an outlet pipe 27, which may lead to a storage tankor other receptacle, as-niay be desired. The upper portion of the standpipe is inv communication with a conduit 28 through which air un der pressure may be deliveredto the stand: pipe. This air passes downwardly in the standpipe, and, acting upon the water within the standpipe,- forces the latter downwardly and causes it to rise within the compartments of the interiorly-located pipe structure, said water being caused to rise and overflow in the upper extremities of the said compartments within the reservoir 24. Astlie water rises within the said compartments, air from the jet nozzles 20, 21 and 22 entersthe said compartments and mingles with the whter,'-'forming air bubbles and diminishing specific gravity of the water, according to the-volume of air introduced. These air jet nozzles must be relatively small, so as not to allow a sufiicient quantity of air within the compartments abovethe water level, as to interfere with the raising of tlietwater within the compartments by the pressure of the air upon the water within the standpipe. The bottom of the reservoir 24 is provided with a stufiing box -2, through which the passes, thesaid stuffing'box forming a water-tight joint around-the said pipe structure. This reservoir is also provided with an outlet 30, through which the air that accumulates within the said reservoir may escape.

The combination with a standpipe, whose lower extremity is in communication with a source of water supply, of a pipe structurewithin the standpipe fiorming the central portion of the'space within tliezpipje into a plurality of compartments of relatively small cross sectional area, both extremities of the said compartments being open, their lower extremities being in communication with a source of water supply within the standpipe, means for introducing air under pressure within the sta ndpipe above the level of the water, the various compartments of the pipe structure being in communication with the air within the standpipe to permit the entrance .of relatively small air jets, for the purpose set...v
